-LRB- CNN -RRB- -- A Chinese man captured by federal agents in 2011 has pleaded guilty in a federal court for pirating copyrighted software worth more than $ 100 million , officials of ICE announced Tuesday .

Xiang Li , 36 , of Chengdu will be sentenced May 3 , by a judge in Wilmington , Delaware , and could receive a sentence of up to 25 years .

Authorities last April disclosed that Li had been captured by agents of Homeland Security Investigations in Saipan in the Northern Mariana Islands .

`` Li mistakenly thought he was safe ... hiding halfway around the world in cyberspace anonymity , '' ICE Director John Morton said Tuesday .

An alleged co-conspirator , Chun Yan Li , remains a fugitive and is believed to be in Chengdu , ICE says .

Officials say the men were indicted by a Delaware grand jury on charges of software piracy and illegally exporting technology to China .

Li admitted to selling the pirated materials through his website Crack99 which authorities say harmed more than 150 U.S. companies . They were sold to thousands of customers in 28 states and 60 foreign countries .

The software covered a wide range of applications used in manufacturing , engineering , space exploration , storm water management , explosives simulation and manufacturing plant design .

One of their largest customers was a former electronics engineer at NASA 's Goddard Space Flight Center in Maryland , who pleaded guilty to copyright infringement last April .

Officials said Cosburn Wedderburn had purchased more than $ 1 million in pirated software from the Chinese conspirators .
